The remuneration in Nordic countries is essentially without any reference to
wave power (there is a mention in the Danish tariff system but the level
shows that it is a token gesture).
The Scottish Government has used their prerogative to self determine
renewable energy support. The level is based on the expected cost of wave
power today and will be reviewed at certain intervals. However, existing
plants will keep the level at their introduction, so called grandfathering.
(Note: Tidal power receives 3 ROC’s)
The UK support level is appreciated to be too low but is expected, at least
initially, to be combined with capital support as well.

Wave power projects in the near
future
There have so far been relatively few wave power demonstration projects at
anything near full scale and grid connected. However, there are number of
projects announced to be deployed the near future. In common all have been
allocated large grants from public sources. As full-scale demonstrations needs
substantial investments with uncertain returns a high degree of public funding
at this stage is more or less a necessity. However, public funding sources are
not inexhaustible and there is a possibility that the gap between developers
will increase depending on who has received funding or not. Furthermore, it
will be very important for the selected developers to be sufficiently successful
otherwise there is a risk of waning interest from authorities.
The following table lists wave power devices at full or large scale and grid
connected to be deployed 2010-2011.

* Wave and Tidal Energy Support Scheme (WATES), £10 Million allocated to wave and tidal
projects. Now to be followed by the £12 Million WATERS fund.
** Marine Renewables Proving Fund (MRPF), a one-off £22 Million allocation shared by four tidal
projects and the two wave projects above out of some 30 applicants.
At the close of 2010 the first Pelamis P2 is in place at EMEC while the
Mutriuku project is on way although it has suffered storm damage. The CETO
and Powerbuoy will be delayed until 2011 but are in the process of being
built. The Seabased project has received an environmental permit and is
understood to be waiting for a green light from the EU commission regarding
the grant from the Swedish government. Thus no deployment has taken place
yet.
Looking beyond 2011 plans tend to be more tentative, however one project
merits mentioning. RWE npower plans to build a 4MW wave power station on
the Scottish Island of Siadar to be in operation 2012 with a £6 Million grant
from the Scottish government’s WATERS fund. It will consist of 40 100 kW
Wavegen turbines incorporated in a newly built breakwater.
